Ratios and Proportions in Cereal and Paint

Kaley introduces part-part-whole ratios using paint mixing and cereal examples. The lesson covers how to calculate and compare ratios, convert them to fractions and percentages, and apply these concepts in real-world scenarios. The CK-12 simulation is used to mix paint colors, and cereal is used to demonstrate ratios of different parts. The video concludes with converting ratios to fractions and percentages.
